POCKET- l N HALER.

SPECIFICATION forming part of Letters Patent No. 308,640, dated December2, 1884.

Application filed September 6, 1884. (No model.)

To all whom it may concern.-

Be it known that I, SAMUEL SwARTz, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Pocket-Inhalers; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this specification.

The object of my invention is to produce a neat, cheap, and usefulpocket-inhale-r,whereby medical properties can be introduced into thenose, mouth, and lungs by inhalation.

To accomplish this the invention consists in providing a tube and coreof certain construction, which will be more fully hereinafter shown anddescribed.

In the drawings, Figure 1 is a view of my inhaler. Fig. 2 is a centrallongitudinal section of Fig. 1, showing the interior construction. Fig.3 represents the core.

Like letters in all the figures refer to corresponding parts.

Referring to the drawings, A represents the tube or outside case, whichmay be made of any material that will resist the action of acids or anymedical compound which may be used to come in contact therewith, butpreferably made of hard rubber, the size to be about two inches long andthree-quarters of an inch diameter, the ends or nozzles A A of which areabout three-quarters of an inch long, and reduced in diameter to aboutthree-eighths of an inch, as shown. The object of this is to admit of aconvenient size for introducing into the nose or mouth. One end,A, mustbe attached to the tube by screw-threadsAi, in order to detach the samefor the purpose of putting the core in the tube.

13 represents a groove out near one end of the instrument, as shown. Theobject of this is to attach a cord, 7), for the purpose of holding thecorks so as not to become detached from the instrument, and also todistinguish between the ends, to enable the operator to choose eitherend to use in the nose or month, which can be done as well in the darkby feeling as by seeing, and therefore adapted to avoid the necessity ofusing one end for both nose and mouth. Each end of the instrument isprovided with a cork, b, which is attached to the cord aforesaid.

0 represents the core, which is made of porous terra-cotta, whichconsists of a mixture of clay and sawdust, or ground corn or likematerial, that will produce porosity in burning. The proportion of claymay be one to two or three of porous material, as required, the same tobe mixed with water to a consistency-suitable to be molded or pressedthrough a die of the size required to fill the parallel part of thetube, which is then dried and burned in a kiln to produce the pores.

In order to charge my inhaler, fifty to seventy-five drops of the liquidmedical compound may be dropped into either end of the tube, and thecore will immediately absorb the same and retain it ready for use.

The advantages of my invention overothers consist in the unchangeablenature of the material of which the core is made, it beingindestructible by fire or frost, and will not expand or shrink by changeof temperature, and it will resist the action of the strongest acids; itwill not stick to the tube by the ac-.

tion of evaporation of the inhalent; it can be taken out of the tube, ifrequired, and cleansed by washing or burning. Second, it will readily beseen that the abovedescribed core, having a uniform and fixed porosity,will admit of a fixed quantity of air, which may be drawn through;consequently there is always it'lllllfOllll action and effect producedto those using inhalents. Third, the case being of such form or shape toadmit of attaching a cord near one end, to which the corks are attached,by which means they cannot be detached from the instrument and lost.

I am aware that porous terra-cotta made from clay and sawdust is notnew; but I am not aware that it has ever been used for an inhaler, bywhich means, I think, it will effect a new and useful result by a newmode of action. 7

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with the case consisting of the tube A, having theopenings A and A name to this specification in the presence of ofreduced size at each end thereof, the end two subscribing Witnesses. Abeing IElllOVZLblY secured to the tube A, I r of the core 0, composed ofporous terraJ-cotta, SAMUEL 5 the Whole forming an inhaler,substantially as XVitnesses:
